7409.31.10.00 - Of a thickness of 5 mm or more

This HTS category, 7409.31.10.00, specifically classifies plates, sheets, and strip of copper-tin base alloys (bronze) that are presented in coils and have a thickness of 5 millimeters or more. These are substantial forms of bronze, intended for applications where rigidity and a significant cross-section are required. The classification focuses on the physical dimension of thickness as the primary differentiating factor.

It is crucial to distinguish this category from its sibling, 7409.31.90.00, which covers bronze plates, sheets, and strip in coils of a thickness less than 5 millimeters. Therefore, the definitive criterion for inclusion in this subcategory is the measurement of the material's thickness; if it is 5 mm or greater, it falls here, whereas if it is less than 5 mm, it would be classified under the sibling category.

As this is a leaf node in the HTS structure, there are no further subcategories for this specific item. Classification is finalized at this level based on the material composition (copper-tin base alloys), form (plates, sheets, strip in coils), and the specified thickness of 5 mm or more. Examples of goods classified here might include heavy gauge bronze sheeting used in industrial fabrication or specialized metalwork requiring substantial bronze material.
